This document discusses strategies for building social presence in online courses. It begins by introducing the authors, Patrick Lowenthal and Joanna Dunlap, and their backgrounds. It then explores what social presence means and why it matters for engagement. The authors investigated lessons learned about social presence through two inquiries. The first identified themes around connections, working together, access, fun, and the unexpected. The second examined high impact and low-cost strategies like orientations, feedback, discussions, and introductions. The document concludes by matching high- and low-tech tools to foster social presence and engagement.
